Re: [Phys-L] impacts

I’m too lazy (code for I have other things to do) to experiment before suggesting, but …


The Vernier force plate might give you an idea for a base ball against a plate w/ a high force constant.  I’m too long using the interface, so I can’t even guess the time resolution.  Exploration of Vernier’s site may reveal a report on this experiment.

bc has force plate, suspects time resolution insufficient, and lazy.
